Greetings,
I am having issues with my Geant4 code. I am currently getting this error:

I am only receiving this error when the simulation is being ran in multithreaded mode. When running in single thread, the errors never appear. Also, the physical volume “Granite” is misnamed, it is a volume of air that is being used to define a local electric field. Any insight will be appreciated. Thank you.
